Abstract

Measurements of the specific heat, resistivity, and magnetoresistance of CeCuxAg1-xAl3 classify this series of alloys as Kondo lattices with a magnetically ordered ground state. Though isoelectronic substitutions are performed, significant changes of the electronic density of states occur, causing a strong concentration-dependent variation of the antiferromagnetic ordering temperature.
